A" feed lever 54 is pivoted at 55 on the card i l. v suppor l2 and is provided with a spring 56 and present ng 15 1 n; rate adjacent a card which normally holds the lever 54 against a stop 45 .ch'iite -l I. The record r is as being of pin 5]. A fed pawl 60 for the'ratchet wheel 52 45 the which the card revamps positioned is pivoted at 6| to the upper end of the feed vertically by a card" support l2, slidable in grooves lever 54 and is yieldingly drawn downward ll in the-sides of the c chute H. 7 against a; stop 62 b y a spring 63 which connects The card suppo is' s own as being connected pins in the'sides of the lever and pawl 60. 50 by alin'k I Sto'the nam s-d of a lever l6, pivoted A latch III is" pivoted at H to the lower end of 5( I at l l and adaptedto be actuated by a em or the bell crank 30 and at its outer end is proother suitable in ciiani'sni. tinie controlled or vidd' with s hook adapted to engage the lower otherwis riots end of the feed lever 51!.- A sn mg'n is'secured to pins in' the'h'ell cianlt Q0 and latch 10 respecmay and tends to swing the latch 10 upward. 6!

The latch 10 has a cam portion l! on its upper face adapted to engage a stop pin 18 under certain conditions.

A spring Ill acts to move the bell crank to the position shown in Fig. 1, in which it engages a stop pin II. The flexible contact arm 38 has a projection ll positioned for engagement by the teeth of the star wheel ill. Either the projection II or the star wheel 50 should be or non-conducting material.

Having'described the construction of my improved mechanism, I will now describe the operation thereof. The normal position or the parts has shown in Fig. i, with the offset portion M or the bell crank 30 lifted substantially above the upper edge or the card support l2. When a card is inserted and pressed lightly downward. the onset portion 32 is pressed down against the upper edgeot the card support I! and the lower end of the bell crank 30 is swung to the left in Fig. 1, thereby moving the feed lever 54 and feed pawl I0 to'the position shown in Fig. 3. The feed pawl 00 is thereby moved rearward one tooth relative to theratchet wheel 52 and star wheel 50.

As the parts reach this position, the cam portion I! 0! the latch 10 engages the stop pin 88 and is forced downward to release the ieed lever II, which is thereupon moved to the position shown in Fig. 1 by the tension of the spring 56.

Such movement of the feed lever advances the ratchet wheel 52 and star wheel 50 counterclockwise by one tooth space. During this advance movement, one point 0! the star wheel engages the projection 85 on the flexible arm 35, iorcing the same downward and causing the contacts 33 'and II to be engaged as indicated in'Fig. 4.

During the completion of the advance movement or the star wheel, the engaged point of the star wheel is moved beyond the projection 85, and the flexible arm 38 then swings upward, separating the terminals 33 and I! and breaking the circuit, the parts being then in the position shown in Fig. 5. During the time the circuit was closed, the-solenoid coil 23 was energized and a blow was struck by the hammer ll.

When the pressure of the card is removed, the spring 80 restores the bell crank 30 to initial posi tion and moves the latch 10 to the right to clear the pin .18 and to reengage the lower end oi the feed lever 54.

It thus appears that the operation of the hammer mechanism is initiated by insertion of a card in the card chute and by pressure of the card against the ofl'set portion 32 of the bell crank 30.

qing of the circuit, which events would take place in definite timed relation and regardless of the movement or lack of movement of any other machine part.

While I have shown my invention embodied in a machine in which a movable card support is utilized, it is obvious that my improvements would operate in the same manner in a machine in which the card support was stationary.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set iorth in the claims, but what I claim is:-

1. In a time recording apparatus comprising a card chute, a card support, printing devices adapted to make a record on a card resting on said support, electro-magnetic means to actuate said printing device to make said record, and an electro-circuit for said means, that improvement which consists in providing mechanism to successively close and open said electric circuit, a spring-operated device to actuate said mechanism, and card-engaged means to tension and then release said device as the card is inserted and seated on said support.

2.

3. In a time recording apparatus comprising a card chute, a card support, printing devices adapted to make a record on a card resting on said support, electro-magnetic means to actuate said printing device to make said record, and an electro-circuit for said means, that improvement which consists in providing a star wheel eiiective to successively close and then open said circuit. springoperated means to advance said star wheel step-by-step, and connections through which in sertion of ,a card in said chute first tensions said spring-operated means and then releases said means to actuate said star wheel independent of said electro-magnetic meaans.

4. In a time recording apparatus comprising a card chute, a card support, printing devices adapted to make a record on a card resting on said support, electro-magnetic means to actuate said printing device to make said record, and an electro-circuit for said means, that improvement which consists in providing a control member movably mounted on said support and having a portion positioned in the path of an inserted card and engaged and moved thereby, and a circult-closing mechanism set for operation by such engagement and thereafter effective to automatically close and then open said circuit independently of the position of said card, of said member, of said electro-magnetic means, andoi' any parts actuated thereby.

5. In a timerecording apparatus comprising a card chute, a card support, printing devices adapted to make a record on a card resting on said support, electro-magnetic means to actuate said printing device to make said record, and an electro-circuit for said means, that improvement which consists in providing a control member movably mounted on said support and having a portionpositioned in the path of an inserted card and engaged and moved thereby, mechanism including a spring-operated member for automatically and successively closing and then opening said electric circuit, and connections between said control member and said mechanism through which movement of said control member by insertion of a card in said chute first tensions said spring-operated member and then releases said member to actuate said mechanism.

Card-controlled printing mechanism having electro-magnetic actuating means, a member engaged byth'e edge of the card and movable thereby, a control device for successively closing and opening the electro-magnetic circuit, and feeding means for said control device rendered operative by card-actuated movement of said card-engaged member, but operation of saidi'eeding means to move said control device to close and thereafter open saidcircuit taking place only after release of said. feeding means by said card-engaged member and independently of said cardengaged member and of said electro-magnetic means and of any parts actuated thereby.

8. Card-controlled printing mechanism comprising printing devices having electro-magnetic actuating means, a member engaged by the edge of a card and movable thereby, mechanism for successively closing and opening an electrocircuit for said electro-magnetic means, and connections through which movement of said cardengaged member first sets said mechanism for operation and then releases said mechanism to operate independently to close and thereafter open said circuit without reference to the position of said card-engaged member or of any parts actuated by said electro-magnetic means.
